Hi Aimee - Just an update, the master branch of ActiveCouch now supports 0.8.0 and upwards. I'm still working on the couchify command (as you may notice from the code) so please give it another go!

Aimee, this is again, excellent, thanks for taking the time to write this, and keep it up!

The find/view issue, in my opinion shows that AR is probably not the best model to use with CouchDB. I'm not saying it can't be made to work together, but I think we'd need to bend both parts to something they weren't designed to do. Why is that?

The difference between CouchDB and an RDBMS (that AR is 'just' and object representation of) can be summed up as "RDBMS: Static data & dynamic queries vs CouchDB: Dynamic data & fixed queries". So providing dynamic queries is not exactly CouchDB's strength. This is not a bad thing though, you still can get all the info you need for your application out of CouchDB. Just in a different way. That makes AR probably not the first choice for an OO abstraction layer on top of CouchDB.

To fix the API issues of ActiveCouch, see http://wiki.apache.org/couchdb/BreakingChanges for what has changed in CouchDB.

Again, brilliant content, please continue!

Cheers
Jan

Great series of articles. You've hit a perfect balance between code examples and explanation which has really got me interested in investigating CouchDB. Thanks very much

aimee · 1 year ago

@Jan ... Thank you for your encouragement, and it is really great to hear your opinions. I'm not particularly impressed with ActiveCouch and i don't want to be the one to fix its issues. I have a feeling the RelaxDB Merb plugin will prove to be much more flexible and more suited to CouchDB.

@SD ... Thanks, it's lovely to hear your feedback. I'm glad to be getting other people interested in the Couch! :)

Jup, my comment definitely missed a "In case you want to fix AactiveCouch"... Sorry :-) (New ep tonight? :)

aimee · 1 year ago

Yes, i'm getting on with some more CouchDB tonight. I feel i'm in a race with TopFunky to see if i can get my next part out before the PeepCode! :) Although i'm really very interested to see what Geoffrey has to say about CouchDB and Rails ...!

Geoffrey Grosenbach · 1 year ago

Personally, I think some of these ActiveRecord-ish libraries are overkill. I wrote a simple 60-line wrapper for CouchRest that does most of what you need, and takes advantage of CouchDB's strengths (flexible schema, etc.)

Excellent, thank you Geoffrey! I will take a look.

I'm inclined to agree with you, but to get started i wanted something
that feels familiar for me.

Hi Aimee - Just stumbled upon this blog post. I'm making changes to ActiveCouch this weekend to make it compatible with 0.8.x as well as more Rails-friendly (so a 'couchify' command which will automagically add config files for ActiveCouch to use in your Rails project, etc.)

Been really busy at work, so haven't gotten a chance to catch up with CouchDB awesomeness.

Stay tuned, though :)

aimee · 1 year ago

Nice to hear from you, Arun. Good luck with the new updates - should be exciting! :)

Hi Aimee - I've updated the ActiveCouch wiki where you can read about the latest changes to ActiveCouch and how it integrates much better with Ruby On Rails:

It is not uncommon to have to deal with several constant stores in a single application. A very common approach is to use a relational database that stores paths pointing to files that are stored in a file system.
So you might think as CouchDB as a special "file system" for a special part of your data model.
Also, in larger applications, multiple stores and complex physical architectures are quite common, so don't be shy of using more than one persistent store for your models.
